Do I need a return flight ticket to enter Thailand under the current regulations?

The discussion revolves around the necessity of having a return flight ticket when entering Thailand, particularly under the Certificate of Entry (CoE) requirements. While some travelers reported success boarding flights without a return ticket, others advised securing a cheap onward ticket as a precaution, citing inconsistency in airline and immigration practices. Several comments highlighted experiences with both visa-exempt entries and different visa categories, revealing a general lack of clarity about the enforceability of the return flight requirement.
